I love my Wenger Backpack
It does indeed only have one padded pocket, but it easily has room in the same space at the back for a laptop/tablet in a padded sleeve, kindle goes in the front, phone slips in the top pocket (some kind of ipod holder thing, just right for a phone and the rest of the pocket space is great for pens, leatherman etc). then there's the main compartment which easily has the space for a change of clothes and lunch, and my cables for my chargers handily stashed in the net pocket at the top. then there's another compartment with yet another phone pocket, pen space etc which handily holds my bike lock. And on top of all that I fit a bottle of water in the side. I still have a pocket at the very front free and another side pocket.
Love this bag so much. Used it on three continents for 6 years and while the rubber in the little bungee things on the side is dead, the rest of the bag is still working well if a little scuffed. Cost me £15 in Morgan years back and I can't replace it. Not even with the Wenger messenger back I picked up this year.
